And then the fisheries regulators step in and moratoria are put up, and many of those fisheries have rebounded and rebounded well.

uh it just turns out that the oceans are incredibly productive given a chance and populations will will rebound species that are familiar to us like the bald eagle people may know that in the 1960s because of widespread use of ddt bald eagles and peregrine falcons were devastated they had a lot of trouble with the viability of their chicks so populations crashed

We were down to fewer than 500 mating pairs of bald eagles, the national symbol, by the late 60s. Today, that number is over 70,000 breeding pairs, and the total population is even bigger than that. So when we took the pressure off, when we took away DDT, which was compromising their ability to reproduce, the population came roaring back.

And you can tell the same story of manatees in the waters off Florida, of grizzly bears in the Rockies, of sea otters on the Pacific coast. So individual species can come roaring back.
